AUYTOJMATIC THREAD-BOARD LIFTER.

SPECIFICATION forming part of Letters Patent N o. 737,161,dated August25, 1903. I A Application filed February 14, 1903. Serial No. 143,430.(No model.)

To all whom it may concern/.- v

Be it known that I, WILLIAM E. SHARPLEs,

a citizen of the United States, residing at Fall River, in the county ofBristol and State of M assach usetts,have invented certain new anduseful Improvements in Automatic Thread- Board Lifters; and I do declarethe following to be a full, clear, and exact description of the.

invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being. had to theaccompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

This invention relates to thread-board lifttions and arrangements ofparts, as hereinaf- 1 ter setforth, and particularly pointed out in Inthe accompanying drawings, Figure 1 is a front elevation, partlyinsection, of a portion of a ring-spinning frame equipped with myinvention. Fig. 2 is a side elevation, partly in section, of the same.

The roller-beam A, the thread-board B, hinged thereto at b, theguide-wire O on the thread-board, the spindle-rail D, the spindles E,mounted thereon, the bobbins F on said spindles, the ring-rail G,carrying the ring g and its traveler g, the lifting-rod H, attached tothe ring-rail, the rock-shaft I, carrying an arm K, in the end of whichis a slot 70 for the adjustment of the roller L, on which rests the footH, secured to the lower end of the ringrail-liftin g rod II, and bymeans of which said rod is lifted'and lowered, are all old and may be ofany desired construction.

Secured to the under side of the thread-.

board is-a bent arm M, which passes down- Ward and backward under theroller-beam A. A rearwardly-extending bracket N is bolted to theroller-beam adjacent to said arm, and in its rear forked end is pivoteda cam-lever 0, bearing on the arm M. The pivots of the cam-lever can beadjusted along longitudinal slots n in the bracket to vary'the point ofcontactwith the arm M and thus alter the lift of the thread-board. Thecam can be turned down to depress the arm M andthus tilt up 11;?hethread-board, as shown in dotted lines in ig. 2. g

In order to actuate the cam-lever automat- 6o ically, I provide on therock-shaft I-an arm P, by which is carried an adjustable holder for anupright rod Q, which passes through a fixed guide R and terminates belowthe tail of the cam-lever, with which it is not con- 5 nected. Theadjustable holder preferably consists of a clamp S, composed of twoparts held together by a bolt 3 and clamping the arm P between them. Onepart of this clamp has a wrist-pin s engaging the upperend of a pitmanT, the lower end of which is provided with a sleeve 25, through whichthe rod Q passes and in which it can be longitudinally adjusted by aset-screw t.

The operation of my invention is as follows: When the ring-rail islifted by the rock-arm I, the arm P also raises the rod Q, and as thering-rail nears the top of its Wind the upper end of said rod strikesthe tail of the cam-lever and carries it up, thus causing the cam toforce down the arm M and tilt up the thread-board. By means of the clampthe lift of the rod and of the thread-board canbe regulated, and bymeans of the sleeve and set-screw the moment when the upper end of therod will strike the cam-lever can be accurately timed. I

Having thus described my invention, what I claim is-- Y 1. In aring-spinning frame, the combination with ahinged thread-board, of arearwardly-exteuding arm secured thereto, a lever bearing upon said arm,a reciprocating rod adapted to actuate said lever, and a rockarm on arock-shaft of the machine for iinparting motion to said rod.

2. In a ring-spinning frame, the combination with a hinged thread-board,of a rearwardly-extending arm secured thereto, a lever bearing upon saidarm, a reciprocating 10o rod having one end adjacent to but disconnectedfrom said lever, and an arm on a rockshaft of the machine for actuatingsaid rod.

3. In a ring-spinning frame, the combination with a hinged thread-board,of a rearwardly-extending arm secured thereto, a stationary bracketadjacent to said arm, a camlever pivoted in said bracket, and bearing onsaid arm, a reciprocating rod adapted to actuate said lever, and an armon a rock-shaft of the machine for imparting motion to said rod.

4. In a ring-spinning frame, the combination with a hinged thread-board,of a rear- Wardly-extending arm secured thereto, a stationary forked andslotted bracket adjacent to said arm, a cam-lever having its pivotsadjustably mounted in said slotted bracket, said cam-lever bearing onthe arm, a reciprocating rod for actuatingsaid cam-lever, and means foractuating said rod.
